Rare black mid-century modern bedside lamp or table lamp with an adjustable plastic shade. Probably manufactured by wkr leuchten (workshop for artisan interior lighting (=wkr), founded in berlin in the 1920s). Other sources attribute it to the cosack company. 1950s, germany. The lamp's tripod frame consists of conical brass tubes with spheres at the top. It has an e14 edison screw socket. It has been rewired and operates on 110/230 volts. The lampshade's angle can be adjusted very variably using the joint. The lampshade can also be rotated around the socket's axis. The tripod base provides very stable support. Perfect condition! the electrical system has been replaced with a high-quality braided black fabric cable with protective earthing. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution, european plug (up to 250v).the wiring of this item may be original and might need replacement, if not specified otherwise.
